BRUSH-MAKING'TOOL.

SPECIFICATION forming part of Letters Patent No. 252,149, dated January 10, 1852,.

. Application filed October 27, 1881. (No model.)

To all whom it may concern:

Be it known that I, ALBERT P. SMITH, a citizen of the United States, residing in Brooklyn, E. D., Kings county, New York, have invented certain Improvements in Tools for Forcing the Bands or Ferrules on Brushes, of which the following is a specification.

In making a certain kind of brush from bris-.

tles, hair, or fibers of various kinds, and notably in wall or fiat brushes, it is customary to secure the bristles or hair to the handle by forcing over them and the handle embedded in their butts an endless band or ferrule, gen erally made from sheet metal. Cement and nails are used also as an additional security against the escape of the bristles.

It is for the purpose of forcing the ferrule above mentioned to its place that I have invented the instrument which forms the subject of the present application for patent.

In the drawings which serve to illustrate my invention, Figure 1 is a front view of the tool or instrument. Fig. 2 is aplan view of the tool arranged to illustrate its application in the manufacture of brushes. Fig. 3 is a longitudinal vertical section taken in the plane of line 3 3 in Fig. 2.

Fig. 4 shows a band or ferrule such as is usually employed for flat or oval brushes in elevation and plan.

Theinstrument A is formed of four like parts or quarters, of which the curved parts a a, when fitted together, form a flattened-ring of the proper shape to receive thebaud, and the straight parts I) I) form the handles. The iiistrument is made extensible longitudinally by means of extension-rods cc, which pass through the parts a a, set-screws d d being employed to clamp, the parts a a to the rods. It is made expansible laterally by means of screws 0 e, which pass through one side of the handle and screw into the other. Springsff between the parts b I) serve to press them apart as far as the screws 0 will permit.

B is a band of metal or other suitable ma;- terial, made of the proper size to fit the brush.

The mode of using the tool in the operation of making a brush is as follows: The bristles G are selected and their butts dipped in cement. The band B is then slipped over them, and the tool A also, it havingbeen previously adjusted to fit the band. The ends of the bristles are now clamped fast between jaws D of some suitable stationary clamping device, and

the handle E of the brush inserted into the butts of the bristles, and the'latter adjusted around it. The operator now grasps the handle b of the tool A (see Fig. 2) and draws the tool toward the brushhandle. This brings it over the band'B, and then a flange, g, around the inner sides of the parts a takes against the hand and forces it upward or forward over the cemented butts of the bristles and the handle embedded therein, whereby the bristles are forcibly compressed between the band and the handle. The jaws D may now be taken off and the tool A slipped 0d at the flag end of the bristles. The band can then be nailed to afford additional security.

The tool A serves as a re-ent'orce, to back up the band and keep it from bursting as well as to preserve its proper form.

In making flat or oval brushes the thin band tends to assume a circular shape, and this the tool prevents.

lilo not claim the endless band, nor broadly a re-enforce to protect the band while it is be- 7 ing forced on; but

What I do claim is- 1. A tool or instrument forforcing theband 0r ferrule on abrush, made extensible longitudinally and expansible laterally, and provided with aninternal flange to engage the ferrule while it is being forced, constructed and arranged to operate substantially as set forth.

2. A tool for forcing the band or ferrule on a flat brush, made from four like parts or sec; tions, on 1), arranged to slide on rods 0, whereby the tool is made capable of extension and adjustment longitudinally, and provided with expanding screws,whereby the tool is made capable of expansion and adjustment laterally, substantially as and for the purposes set forth.

3. The combination, to form atool for forcing a band or ferrule on a brush, of the curved parts a (I, provided with flange g, the handles ()1), the extension rods c e, and screws 0, all constructed and arranged substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

ALBERT P. SMITH.
